Thus, the synchronization of both random numbers for deciding the initial value at the time of timer interruption generation is prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention provides a pachinko gaming machine, a slot machine, or the like that can be controlled to a specific gaming state advantageous to a player when a display result of variable display of a plurality of types of identification information that can identify each becomes a specific display result. It relates to gaming machines.

  As a gaming machine, a game medium such as a game ball is launched into a game area by a launching device, and when a game medium wins a prize area such as a prize opening provided in the game area, a predetermined number of prize balls are paid out to the player. There is something to be done. Furthermore, there is provided a variable display unit capable of changing the display state, and configured to give a predetermined game value to the player when the display result of the variable display unit is in a predetermined specific display mode. is there.

  Note that the game value is the right that the state of the variable winning ball device provided in the gaming area of the gaming machine is advantageous for a player who is likely to win a ball, or the advantageous state for a player. In other words, or a condition for winning a prize ball is easily established.

  In a pachinko gaming machine, the fact that the display result of the variable display unit that displays the special symbol (identification information) is a combination of specific display modes that are set in advance is generally referred to as “big hit”. When the big hit occurs, for example, the big winning opening is opened a predetermined number of times, and the game shifts to a big hit gaming state where the hit ball is easy to win. And in each open period, if there is a prize for a predetermined number (for example, 10) of the big prize opening, the big prize opening is closed. And the number of times the special winning opening is opened is fixed to a predetermined number (for example, 15 rounds). An opening time (for example, 29.5 seconds) is determined for each opening, and even if the number of winnings does not reach a predetermined number, the big winning opening is closed when the opening time elapses. Further, when a predetermined condition (for example, winning in the V zone provided in the big prize opening) is not established at the time when the big prize opening is closed, the big hit gaming state is ended.

  In addition, the symbols other than the symbol that becomes the final stop symbol (for example, the middle symbol of the left and right middle symbols) on the variable display section are continuously stopped for a predetermined time, stopped, swung, and enlarged. The possibility of big hits continues before the final result is displayed due to a reduced or deformed state, or multiple symbols changing synchronously with the same symbol, or the position of the display symbol changing. An effect performed in a state in which the player is in a state (hereinafter, these states are referred to as reach states) is referred to as reach effect. Further, the reach state and its state are referred to as a reach mode. Furthermore, variable display including reach production is called reach variable display. And when the display result of the symbol variably displayed on the variable display portion is not a specific display result, it becomes “out of” and the variability display state ends. A player plays a game while enjoying how to generate a big hit.

  In such a gaming machine, when a predetermined condition (for example, a start winning as a variable display start condition) is satisfied, a big hit determining random number for use in determining whether or not to win is generated, and the random number of the big hit determining random number Is matched with a predetermined value determined in advance, it is controlled to be a “big hit” (see Patent Document 1).

  In such a gaming machine, an initial value determining random number for updating the initial value of the jackpot determining random number at a predetermined timing is used, so that the big hit determining random number and the initial value determining random number are not synchronized. Some are configured to update the initial value determination random number in an infinite loop (see Patent Document 1).

JP 2000-107387 A

  In the gaming machine described in Patent Document 1, the initial value determination random number is updated in an infinite loop, thereby preventing the big hit determination random number and the initial value determination random number from being synchronized.

  There are multiple types of big hits, such as big hits with conditions for transitioning to probable state, big hits with conditions for transitioning to short-time states, and normal big hits without conditions for transitioning to other gaming states. May have been. When a random number (a big hit type determining random number) is used to determine which type of jackpot to be used when a big hit occurs, avoiding illegal targeting of a specific type of jackpot Therefore, similar to the big hit determining random number, the initial value determining random number for updating the initial value of the big hit type determining random number at a predetermined timing is used, and the big hit type determining random number and its initial value determining random number are used. In order to prevent them from being synchronized with each other, it is conceivable that the initial value determination random number update process is repeatedly executed in the remaining time of the game control process periodically executed by a timer interrupt.

  Then, in order to ensure that the initial value determination random number update process is performed in the extra time of the game control process, it is conceivable to set the interrupt prohibited state during the execution period of the update process.

  However, if the update process of the initial value determination random number in the big hit determination random number and the update process of the initial value determination random number in the big hit type determination random number are executed as an interrupt prohibited state in the remaining time of the game control process, Since it is updated synchronously (synchronization occurs every several cycles), there is a problem that a specific type of jackpot may be illegally targeted at the update timing of the initial value there were.

  Therefore, the present invention can prevent the initial value determination random number in the jackpot determination random number and the initial value determination random number in the jackpot type determination random number from being synchronized with each other. It is an object of the present invention to provide a gaming machine that can prevent illegal targeting.

  The gaming machine according to the present invention has a specific gaming state that is advantageous to the player when the display result of the variable display of a plurality of types of identification information that can be distinguished from each other becomes a specific display result (for example, the same jackpot symbol in the middle left and right) A gaming machine that can be controlled (for example, a big hit gaming state), comprising game control means (for example, a CPU 56) for controlling the progress of the game, and the game control means can control a plurality of types of games after controlling to a specific gaming state. A game state control means for controlling to any one of the game states (for example, a part for executing a process for setting a probability change flag or a short time flag in step S308 in the game control means), and whether or not to set a specific game state Numerical data for determining a specific gaming state used for determination (for example, random number for determining big hit: random 1) is determined in advance as numerical data for first initial value (for example, run Specific gaming state updated from a first initial value (for example, a random 1 initial value determining random number (random 7) stored in the random 1 initial value buffer) based on the random initial value determining random number 1) Numerical data updating means for determination (for example, a part for executing steps S401 to S403 in the game control means) and first initial value updating means for updating the first initial value numerical data (for example, steps S421 to S1 in the game control means) S423 is executed) and the specific gaming state determination numerical data is the same value as the specific numerical data (for example, the random 1 initial value determination random number (random 7) stored in the random 1 initial value buffer). First initial value changing means for changing the first initial value based on the first initial value numerical data (example: numerical data) For example, a part for executing steps S404 to S406 in the game control means) and game state type determination numerical data (for example, a jackpot symbol determination random number) used for determining which of the plurality of types of game states to use. : Random 3) based on predetermined second numerical data for initial values (for example, random 3 initial value determination random number: random 8). For example, random 3 stored in the random 3 initial value buffer. The type determination numerical data update means (for example, the part that executes steps S407 to S409 in the game control means) updated from the initial value determination random number (random 8 value) and the second initial value numerical data are updated. Second initial value updating means (for example, a part for executing steps S427 to S429 in the game control means) Minutes) and the game state type determination numerical data are predetermined numerical data (for example, numerical data having the same value as the random 3 initial value determination random number (random 8) stored in the random 3 initial value buffer) And a second initial value changing means for changing the second initial value based on the second initial value numerical data (for example, a part for executing steps S410 to S412 in the game control means). A process of updating the first initial value numerical data by the initial value updating means (for example, step S18) and a process of updating the second initial value numerical data by the second initial value updating means (for example, step S22) are repeated. Performs main processing (for example, the main routine of step S16 to step S23 shown in FIG. 4) and occurs every predetermined time (for example, 2 ms) Based on the occurrence of the ima interrupt, the main process is interrupted, and the specific gaming state determination numerical data updating means is updated by the specific gaming state determination numerical data updating means (for example, steps S401 to S403 in step S33); Processing for updating the first initial value numerical data by the initial value updating means (for example, steps S421 to S423 in step S34), and processing for changing the first initial value by the first initial value changing means (for example, step S405 in step S33) To S406), processing for updating the game state type determining numerical data by the type determining numerical data updating means (for example, steps S407 to S409 in step S33), and second initial value numerical data by the second initial value updating means. (For example, step S35 in step S35) 27 to S429) and a game control process (for example, a timer interrupt process shown in FIG. 5) including a process for changing the second initial value by the second initial value changing means (for example, steps S411 to S412 in step S33). In the main process, the timer interrupt is performed before executing the process for updating the first initial value numerical data (for example, step S18) and the process for updating the second initial value numerical data (for example, step S22). A process of setting an interrupt prohibited state in which execution of the base game control process is prohibited (for example, steps S16 and S21), a process of updating the first initial value numerical data, and a process of updating the second initial value numerical data. Processing for setting an interrupt-permitted state permitting execution of game control processing based on timer interruption after each execution (for example, steps S19 and S23) And executing.

  In the main process, the game control means updates the second initial value numerical data and the process for setting the interrupt permission state after executing the process of updating the first initial numerical data (for example, step S19). Program counter update processing (for example, step S20 in the game control means) in which only a predetermined number of program counters are updated during the processing of setting the interrupt disabled state before the processing is executed (for example, step S21). Is preferably performed.

  In the main process, the game control means executes a process (for example, step S19 shown in FIG. 14) for setting the interrupt permitted state after executing the process of updating the first initial value numerical data, A standby process (for example, steps S20b to S20c) in which the progress of the main process is in a standby state is executed until the standby period elapses, and after the standby process is completed, before the process of updating the second initial value numerical data is executed. It is preferable to execute a process for setting the interrupt disabled state (for example, step S21 shown in FIG. 14).

  The game control means may be configured to include a predetermined period setting means (for example, step S20a) that randomly sets the predetermined period.

  The game control means sets the interrupt permission state after executing the process of updating the first initial value numerical data (for example, step S19 shown in FIG. 15) and the process of updating the second initial value numerical data. The execution period variation process (for example, step S20d) in which the execution period of the process differs depending on the predetermined execution condition is set between the process for setting the interrupt disabled state before executing (for example, step S21 shown in FIG. 15). It may be configured to execute.

  The game control means performs at least one of processing (for example, step S421) for updating the first initial value numerical data (for example, step S421) and processing for updating the second initial value numerical data (for example, step S427). ), An update value determination process (for example, a process of updating the random number 1 initial value determination random number generation counter to an arbitrary value indicated by the predetermined random number generation counter in step S421). It may be configured to execute.

  According to the first aspect of the invention, the process of updating the first initial value numerical data by the first initial value updating means and the process of updating the second initial value numerical data by the second initial value updating means. The main process is repeatedly performed, and the main process is interrupted based on the occurrence of a timer interrupt that occurs every predetermined time, and the specific gaming state determination numerical data is updated by the specific gaming state determination numerical data updating means. Processing, processing for updating the first initial value numerical data by the first initial value updating means, processing for changing the first initial value by the first initial value changing means, and gaming state by the type determining numerical data updating means A process for updating the type determining numerical data, a process for updating the second initial value numerical data by the second initial value updating means, and a process for changing the second initial value by the second initial value changing means. In the main process, a game control process based on a timer interrupt is executed before executing a process for updating the first initial value numerical data and a process for updating the second initial value numerical data. A game based on a timer interrupt after executing a process for setting an interrupt prohibited state for prohibiting execution of the data, a process for updating the numerical data for the first initial value, and a process for updating the numerical data for the second initial value And a process of setting the interrupt permission state to permit the execution of the control process. Therefore, the update process of the first initial value numeric data and the update process of the second initial value numeric data in the main process are performed. The game control process based on the occurrence of the timer interrupt can be executed between the first initial value numerical data and the second initial value numerical data when the timer interrupt occurs. It is possible to avoid in the state, it is possible to prevent the occurrence of a specific game state of a particular type based on fraud.

  According to the second aspect of the present invention, the game control means sets the interrupt permission state after executing the process of updating the first initial value numerical data in the main process and the second initial value numerical data. Since the program counter update process is performed only to update a predetermined number of program counters before the process of setting the interrupt disabled state before executing the process of updating the It is possible to more reliably execute the game control process based on the occurrence of the timer interrupt between the update process of the first initial value numerical data and the update process of the second initial value numerical data.

  In the invention according to claim 3, the game control means performs a predetermined standby after executing the process of setting the interrupt permission state after executing the process of updating the first initial value numerical data in the main process. A standby process that sets the progress of the main process to a standby state is executed until the period elapses, and after the standby process is completed, the interrupt disabled state is set before the process of updating the numerical data for the second initial value is executed. Since the process is configured to be executed, game control based on the occurrence of a timer interrupt between the update process of the first initial value numeric data and the update process of the second initial value numeric data in the main process The process can be executed more reliably.

  In the fifth aspect of the invention, the game control means performs a process of setting the interrupt permission state after executing a process of updating the first initial value numerical data and a process of updating the second initial value numerical data. Since it is configured to execute an execution period variation process in which the execution period of the process is different depending on a predetermined execution condition between the process set to the interrupt prohibited state before the execution, the first process in the main process Between the update process of the initial value numerical data and the update process of the second initial value numerical data, the period during which the timer interrupt can be generated can be randomized, and the game control is based on the occurrence of the timer interrupt. The process can be executed randomly.

  In the invention according to claim 6, the game control means updates the value in at least one of the process of updating the first initial value numerical data and the process of updating the second initial value numerical data. Since the update value determination process for randomly determining the initial value numerical data is improved, the randomness of at least one of the first initial value numerical data and the second initial value numerical data can be improved. it can.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, the overall configuration of a pachinko gaming machine that is an example of a gaming machine will be described. FIG. 1 is a front view of a pachinko gaming machine as viewed from the front. In the following embodiments, a pachinko gaming machine will be described as an example. However, the gaming machine according to the present invention is not limited to a pachinko gaming machine, and can be applied to other gaming machines such as a slot machine.

  The pachinko gaming machine 1 includes an outer frame (not shown) formed in a vertically long rectangular shape, and a game frame attached to the inside of the outer frame so as to be opened and closed. Further, the pachinko gaming machine 1 has a glass door frame 2 formed in a frame shape that is provided in the game frame so as to be opened and closed. The game frame includes a front frame (not shown) installed to be openable and closable with respect to the outer frame, a mechanism plate to which mechanism parts and the like are attached, and various parts attached to them (excluding a game board described later). Is a structure including

  As shown in FIG. 1, the pachinko gaming machine 1 has a glass door frame 2 formed in a frame shape. On the lower surface of the glass door frame 2 is a hitting ball supply tray (upper plate) 3. Under the hitting ball supply tray 3, an extra ball receiving tray 4 for storing game balls that cannot be accommodated in the hit ball supply tray 3 and a hitting operation handle (operation knob) 5 for launching the game balls are provided. A game board 6 is detachably attached to the back surface of the glass door frame 2. The game board 6 is a structure including a plate-like body constituting the game board 6 and various components attached to the plate-like body. A game area 7 is formed on the front surface of the game board 6.

  Near the center of the game area 7, there is provided a variable display device (special symbol display device) 9 including a plurality of variable display portions each variably displaying a symbol as identification information. The variable display device 9 has, for example, three variable display portions (symbol display areas) of “left”, “middle”, and “right”. In addition, the variable display device 9 is provided with four special symbol start memory display areas (start memory display areas) 18 for displaying the number of effective winning balls that have entered the start winning opening 14, that is, the start memory number. Each time there is a valid start prize, the display color changes (for example, changes from blue display to red display), and the start storage display area is increased by one. Each time the variable display of the variable display device 9 is started, the start memory number display area where the display color is changed is reduced by 1 (that is, the display color is returned to the original). In this example, since the symbol display area and the start memory display area are provided separately, the start memory number can be displayed even during variable display. The start memory display area may be provided in a part of the symbol display area. Further, the display of the start memory number may be interrupted during variable display. In this example, the start memory display area is provided in the variable display device 9. However, a display (special symbol start memory display) for displaying the start memory number may be provided separately from the variable display device 9. Good.

  Below the variable display device 9, a variable winning ball device 15 is provided as a start winning port 14. The winning ball that has entered the start winning opening 14 is guided to the back of the game board 6 and detected by the start opening switch 14a. A variable winning ball device 15 that opens and closes is provided below the start winning opening 14. The variable winning ball device 15 is opened by a solenoid 16.

  An open / close plate 20 that is opened by a solenoid 21 in a specific gaming state (big hit state) is provided below the variable winning ball device 15. The opening / closing plate 20 is a means for opening and closing a large winning opening (variable winning ball apparatus). Of the winning balls guided from the opening / closing plate 20 to the back of the game board 6, the winning ball entering one (V winning area: special area) is detected by the V count switch 22, and the winning ball from the opening / closing board 20 is counted. 23. On the back of the game board 6, a solenoid 21A for switching the route in the special winning opening is also provided.

  When a game ball wins the gate 32 and is detected by the gate switch 32a, the variable display of the normal symbol display 10 is started. In this embodiment, variable display is performed by alternately lighting the left and right lamps (a symbol can be visually recognized when the lamp is lit). For example, if the right lamp is lit when the variable display ends, it is a win. When the stop symbol on the normal symbol display 10 is a predetermined symbol (winning symbol), the variable winning ball device 15 is opened for a predetermined number of times. In the vicinity of the normal symbol display 10, a normal symbol start memory display 41 having a display unit with four LEDs for displaying the number of winning balls entered into the gate 32 is provided. Each time there is a prize at the gate 32, the normal symbol start memory display 41 increases the number of LEDs to be turned on by one. Each time variable display on the normal symbol display 10 is started, the number of LEDs to be lit is reduced by one.

  The game board 6 is provided with a plurality of winning holes 29, 30, 33, 39, and winning of game balls to the winning holes 29, 30, 33, 39 is performed by winning hole switches 29a, 30a, 33a, 39a, respectively. Detected. Each winning opening 29, 30, 33, 39 constitutes a winning area provided in the game board 6 as an area for accepting game media and allowing winning. The start winning opening 14 and the big winning opening also constitute a winning area that accepts game media and allows winning. Around the left and right of the game area 7, there are provided decorative lamps 25 blinking and displayed during the game, and at the lower part there is an outlet 26 for absorbing a game ball that has not won a prize. Two speakers 27 that emit sound effects are provided on the left and right upper portions outside the game area 7. On the outer periphery of the game area 7, a top frame lamp 28a, a left frame lamp 28b, and a right frame lamp 28c are provided. Further, a decoration LED is installed around each structure (such as a big prize opening) in the game area 7. The top frame lamp 28a, the left frame lamp 28b, the right frame lamp 28c, and the decoration LED are examples of a decorative light emitter provided in the gaming machine.

  In this example, a prize ball LED 51 that is lit while paying out a prize ball is provided in the vicinity of the left frame lamp 28b, and a ball break LED 52 that is lit when the refill ball is cut is provided in the vicinity of the top frame lamp 28a. It has been. As described above, the pachinko gaming machine 1 of this embodiment is provided with lamps and LEDs as light emitters in various places. In addition, a prepaid card unit (hereinafter referred to as “card unit”) that enables ball lending by inserting a prepaid card is installed adjacent to the pachinko gaming machine 1 (not shown).

  The card unit includes, for example, a use indicator lamp that indicates whether or not the card unit is in a usable state, a connection table direction indicator that indicates which side of the pachinko gaming machine 1 corresponds to the card unit, When checking the card insertion indicator lamp indicating that the card is inserted, the card insertion slot into which the card as a recording medium is inserted, and the card reader / writer mechanism provided on the back of the card insertion slot A card unit lock is provided to release the unit.

  The game balls launched from the hit ball launching device enter the game area 7 through the hit ball rail, and then descend the game area 7. When the game ball enters the start winning port 14 and is detected by the start port switch 14a, the special symbol starts variable display (variation) on the variable display device 9 if the variable display of the symbol can be started. If the variable display of the symbol cannot be started, the start memory number is increased by one.

  The variable display of the special symbol on the variable display device 9 stops when a certain time has elapsed. If the combination of special symbols at the time of stoppage is a jackpot symbol (specific display result), the game shifts to a jackpot gaming state. That is, the opening / closing plate 20 is opened until a predetermined time elapses or a predetermined number (for example, 10) of game balls wins. When a game ball wins the V winning area while the opening / closing plate 20 is opened and is detected by the V count switch 22, a continuation right is generated and the opening / closing plate 20 is opened again. The generation of the continuation right is allowed a predetermined number of times (for example, 15 rounds).

  When the combination of special symbols in the variable display device 9 at the time of stopping is a combination of jackpot symbols (probability variation symbols) with probability fluctuations, the probability of the next jackpot increases. That is, it becomes a more advantageous state for the player in the probability variation state.

  When the game ball wins the gate 32, the normal symbol display unit 10 is in a state where the normal symbol is variably displayed. Further, when the stop symbol on the normal symbol display 10 is a predetermined symbol (winning symbol), the variable winning ball device 15 is opened for a predetermined time. Further, in the probability variation state, the probability that the stop symbol in the normal symbol display 10 becomes a winning symbol is increased, and the opening time and the number of times of opening of the variable winning ball device 15 are increased. That is, the opening time and the number of opening times of the variable winning ball apparatus 15 are increased when the stop symbol of the normal symbol is a winning symbol during the probability changing state.

  FIG. 2 is a block diagram illustrating an example of a circuit configuration in the main board 31. 2 also shows the payout control board 37, the effect control board 80, and the like. On the main board 31, a basic circuit (corresponding to a game control microcomputer: game control means) 53 for controlling the pachinko gaming machine 1 according to a program, a gate switch 32a, a start port switch 14a, a V count switch 22, and a count switch 23 , And an input driver circuit 58 for giving signals from the winning opening switches 29a, 30a, 33a, 39a to the basic circuit 53, a solenoid 16 for opening / closing the variable winning ball apparatus 15, a solenoid 21 for opening / closing the opening / closing plate 20, and the inside of the big winning opening And a solenoid circuit 59 for driving the solenoid 21A for switching the path according to a command from the basic circuit 53.

  It should be noted that the gate switch 32a, the start port switch 14a, the V count switch 22, the count switch 23, the winning port switches 29a, 30a, 33a, 39a, and other switches may be referred to as sensors. That is, the name of the game medium detection means is not limited as long as it is a game medium detection means (game ball detection means in this example) that can detect a game ball. Each of the start port switch 14a, the V count switch 22, the count switch 23, and the winning port switches 29a, 30a, 33a, and 39a for performing the winning detection is also a winning detection means. Note that the winning detection means may be configured to collectively detect the respective game balls that have won separately a plurality of winning openings. In addition, even if a pass gate such as the gate switch 32a is used, if a prize ball is to be paid out, a game ball enters the pass gate is a prize, and a switch ( For example, the gate switch 32a) serves as a winning detection means. Furthermore, in this embodiment, since the game balls won in the V winning area are detected only by the V count switch 22, the number of game balls won in the big prize opening is determined by the number detected by the V count switch 22 and the count switch 23. It becomes the sum with the number of detection by. However, the game ball that has won the V winning area may be detected by the V count switch 22 and also by the count switch 23. In that case, the number of game balls won in the big winning opening corresponds to the number detected by the count switch 23.

  A switch common voltage (for example, + 12V) is supplied to each of the start port switch 14a, the count switch 23, and the winning port switches 29a, 30a, 33a, and 39a. A switch common monitoring circuit 71 for monitoring the voltage is mounted. When the switch common monitoring circuit 71 detects that the switch common voltage has decreased to a predetermined value, the switch common monitoring signal input to the basic circuit 53 is turned off.

  Further, according to the data given from the basic circuit 53, the jackpot information indicating the occurrence of the jackpot, the effective starting information indicating the number of starting winning balls used for starting the variable display of the symbols in the variable display device 9, the probability variation has occurred. An information output circuit 64 for outputting an information output signal such as probability variation information indicating the above to an external device such as a hall computer is mounted.

  A basic circuit 53 realized by a game control microcomputer includes a ROM 54 for storing a game control (game control) program and the like, and storage means used as a work memory (variation data storage means for storing fluctuation data). A RAM 55, a CPU 56 that performs control operations according to a program, and an I / O port unit 57 are included. In this embodiment, the ROM 54 and the RAM 55 are built in the CPU 56. That is, the CPU 56 is a one-chip microcomputer. The one-chip microcomputer only needs to have at least the RAM 55 built in, and the ROM 54 and the I / O port unit 57 may be externally attached or built in. Since the CPU 56 executes control according to the program stored in the ROM 54, the CPU 56 executes (or performs processing) hereinafter, specifically, the CPU 56 executes control according to the program. is there. The same applies to CPUs mounted on substrates other than the main substrate 31. The game control means is realized by a basic circuit 53 realized by a game control microcomputer, but is mainly realized by a CPU 56 that executes control according to a program in the game control microcomputer.

  In addition, the RAM 55 is a backup RAM as a nonvolatile storage means that is partially backed up by a backup power source created on a power supply board (not shown) provided in the gaming machine. That is, even if the power supply to the gaming machine is stopped, a part of the contents of the RAM 55 is stored for a predetermined period (until the power supply of the backup power supply is disabled). In this example, at least data corresponding to the game state, that is, the control state of the game control means (a special symbol process flag or the like) is stored in a backup RAM area (an area where power is backed up in the RAM 55: an example of storage means for game control backup). Saved in. The data corresponding to the control state of the game control means is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like occurs. In this example, data indicating the number of unpaid prize balls is stored in a non-backup RAM area (an area in the RAM 55 where power is not backed up: an example of a game control storage means). Note that data indicating the number of unpaid prize balls may be stored in the backup RAM.

  In addition, a reset signal and a power-off signal from the power supply board are input to the basic circuit 53 (specifically, an input port). Further, a clear signal from the clear switch 921 is input to the input driver circuit 58.

  The hitting ball launching device for hitting and launching the game ball includes a launch motor 94 controlled by a circuit on the payout control board 37, and the game ball is launched toward the game area 7 by the rotation of the launch motor 94. A drive signal for driving the firing motor 94 is transmitted to the firing motor 94 via the touch sensor substrate 91. The touch sensor detects that the player is touching the operation knob (hitting ball handle) 5 and a signal from the touch sensor is mounted on the touch sensor substrate 91 (the player touches the operation knob 5). Is transmitted to the payout control board 37 via a circuit including a detection circuit for detecting whether or not it is touched. The circuit on the payout control board 37 stops the driving of the firing motor 94 when the signal from the touch sensor circuit indicates an off state. Note that the operation knob 5 is provided with a touch ring that adjusts the resilience and is a part that the player contacts. In the gaming machine, the touch sensor substrate 91 is disposed between the touch ring and the payout control substrate 37, and is disposed in the vicinity of the touch ring. Specifically, the wiring length between the touch ring and the touch sensor substrate 91 is shorter than the wiring length between the touch sensor substrate 91 and the payout control substrate 37.

  In this embodiment, the effect control means mounted on the effect control board 80 performs display control of the normal symbol start memory display 41 and the decoration lamp 25 provided on the game board 6, and the frame side Display control of the top frame lamp 28a, the left frame lamp 28b, and the right frame lamp 28c. The effect control means mounted on the effect control board 80 also performs display control of the variable display device 9 that variably displays special symbols and the normal symbol display 10 that variably displays normal symbols.

  In addition, the CPU 56 used in this embodiment includes a non-maskable interrupt terminal (NMI terminal) used for generating a non-maskable interrupt (NMI) that cannot be set to interrupt prohibition by software, And an interrupt terminal (INT terminal) used to generate an external interrupt (external interrupt; maskable interrupt that can be disabled by software). However, this embodiment does not use non-maskable interrupts and external interrupts. Therefore, the NMI terminal and the INT terminal are pulled up to Vcc (+5 V) through resistors. Therefore, the input levels of the NMI terminal and the INT terminal are always high, and there is a possibility that the input level of the NMI terminal and the INT terminal falls due to noise or the like, and an interrupt is generated, as compared with the case where the terminal is open. To reduce.

  Next, the operation of the gaming machine will be described. 3 and 4 are flowcharts showing main processing executed by the game control means on the main board 31. FIG. When the gaming machine is turned on and the input level of the reset terminal to which a reset signal is input becomes high, the CPU 56 performs a security check process that is a process for confirming whether the contents of the program are valid. After execution, the main processing after step S1 is started. In the main process, the CPU 56 first performs necessary initial settings.

  In the initial setting process, the CPU 56 first sets the interrupt prohibition (step S1). Next, the interrupt mode is set to interrupt mode 2 (step S2), and a stack pointer designation address is set to the stack pointer (step S3). Then, the built-in device register is initialized (step S4).

  Next, the CPU 56 performs initial setting (step S5) of CTC (counter / timer) and PIO (parallel input / output port), which are built-in devices (built-in peripheral circuits), and then sets the RAM 55 to an accessible state (step S5). S6).

  The CPU 56 used in this embodiment also incorporates an I / O port (PIO) and a timer / counter circuit (CTC). The CTC also includes two external clock / timer trigger inputs CLK / TRG2, 3 and two timer outputs ZC / TO0,1.

  The CPU 56 used in this embodiment is provided with the following three modes as maskable interrupt modes. When a maskable interrupt occurs, the CPU 56 automatically sets the interrupt disabled state and saves the contents of the program counter in the stack.

  Interrupt mode 0: The built-in device that has issued the interrupt request sends an RST instruction (1 byte) or a CALL instruction (3 bytes) onto the internal data bus of the CPU. Therefore, the CPU 56 executes the instruction at the address corresponding to the RST instruction or the address specified by the CALL instruction. At reset, the CPU 56 automatically enters interrupt mode 0. Therefore, when setting to interrupt mode 1 or interrupt mode 2, it is necessary to perform a process for setting to interrupt mode 1 or interrupt mode 2 in the initial setting process.

  Interrupt mode 1: In this mode, when an interrupt is accepted, the mode always jumps to address 0038 (h).

  Interrupt mode 2: A mode in which the address synthesized from the value (1 byte) of the specific register (I register) of the CPU 56 and the interrupt vector (1 byte: least significant bit 0) output by the built-in device indicates the interrupt address It is. That is, the interrupt address is an address indicated by 2 bytes in which the upper address is the value of the specific register and the lower address is the interrupt vector. Therefore, an interrupt process can be set at an arbitrary address (although it is skipped). Each built-in device has a function of sending an interrupt vector when making an interrupt request.

  Therefore, when the interrupt mode 2 is set, it becomes possible to easily process an interrupt request from each built-in device, and it is possible to install an interrupt process at an arbitrary position in the program. . Furthermore, unlike interrupt mode 1, it is also easy to prepare each interrupt process for each interrupt generation factor. As described above, in this embodiment, the CPU 56 is set to the interrupt mode 2 in step S2 of the initial setting process.

  Next, the CPU 56 confirms the state of the clear signal from the clear switch 921 only once (step S7). When the on-state is detected in the confirmation, the CPU 56 executes a normal initialization process (steps S10 to S15).

  If the clear signal is not on, check whether data protection processing of the backup RAM area (for example, power supply stop processing such as addition of parity data) has been performed when power supply to the gaming machine is stopped (Step S8). In this embodiment, when power supply is stopped, a process for protecting data in the backup RAM area is performed. If it is confirmed that such protection processing has been performed, the CPU 56 determines that there is a backup. When it is confirmed that such a protection process has not been performed, the CPU 56 executes an initialization process.

  Whether or not the protection process has been performed depends on the value of the backup monitoring timer stored in the backup RAM area in the power supply stop process described later according to the execution of the data protection process in the backup RAM area (for example, It is confirmed by whether or not 2). Note that such a confirmation method is merely an example. For example, a flag indicating that the data protection process has been executed is set in the backup flag area in the power supply stop process, and the flag is set in step S8. If it is confirmed that there is a backup, it may be determined that there is backup.

  If it is determined that there is a backup, the CPU 56 performs a data check of the backup RAM area (parity check in this example) (step S9). In this embodiment, clear data (00) is set in the checksum data area, and the checksum calculation start address is set in the pointer. Also, the number of checksum calculations corresponding to the number of data to be checksum is set. Then, the exclusive OR of the contents of the checksum data area and the contents of the RAM area pointed to by the pointer is calculated. The calculation result is stored in the checksum data area, the pointer value is incremented by 1, and the checksum calculation count value is decremented by 1. The above processing is repeated until the value of the checksum calculation count becomes zero. When the value of the checksum calculation count reaches 0, the CPU 56 inverts the value of each bit of the contents of the checksum data area and uses the inverted data as the checksum.

  In the power supply stop process, a checksum is calculated by the same process as described above, and the checksum is stored in the backup RAM area. In step S9, the calculated checksum is compared with the stored checksum. When the power supply is stopped after an unexpected power failure or the like, the data in the backup RAM area should be saved, so the check result (comparison result) is normal (matched). That the check result is not normal means that the data in the backup RAM area is different from the data when the power supply is stopped. In such a case, since the internal state cannot be returned to the state when the power supply is stopped, the initialization process (the processes of steps S10 to S15) executed when the power is turned on, not when the power supply is stopped. Execute.

  If the check result is normal, the CPU 56 performs a game state restoration process for returning the internal state of the game control means and the control state of the electric component control means such as the display control means to the state when the power supply is stopped. Specifically, the start address of the backup setting table stored in the ROM 54 is set as a pointer (step S91), and the contents of the backup setting table are sequentially set in the work area (area in the RAM 55) (step S92). ). The work area is backed up by a backup power source. In the backup setting table, initialization data for an area that may be initialized in the work area is set. As a result of the processing in steps S91 and S92, the saved contents of the work area that should not be initialized remain. The portion that should not be initialized is, for example, a portion in which data (such as a special symbol process flag) indicating a gaming state before stopping power supply is set.

  Further, the CPU 56 sets the head address of the backup command transmission table stored in the ROM 54 as a pointer (step S93), and power is supplied to the sub boards (the payout control board 37 and the effect control board 80) according to the contents. Control is performed so that a control command (recovery command) indicating the recovery is transmitted (step S94). Then, the process proceeds to step S15.

  In the initialization process, the CPU 56 first performs a RAM clear process (step S10). The entire area of the RAM 55 may not be initialized, and predetermined data (for example, count value data of a counter for generating a big hit determination random number) may be left as it is. For example, if the count value data of the counter for generating the big hit determination random number is left as it is, the big hit determination random number is generated even if the initialization process is executed by unauthorized means. Therefore, it is difficult to aim at the timing at which the count value of the counter matches the jackpot determination value. Further, the start address of the initialization setting table stored in the ROM 54 is set as a pointer (step S11), and the contents of the initialization setting table are sequentially set in the work area (step S12). By the processing of steps S11 and S12, for example, a normal symbol determination random number counter, a normal symbol determination buffer, a special symbol left middle right symbol buffer, a total prize ball number storage buffer, a special symbol process flag, an award ball flag, a ball break An initial value is set for a flag for selectively performing processing according to a control state, such as a flag or a payout stop flag.

  Further, the CPU 56 sets the start address of the initialization command transmission table stored in the ROM 54 as a pointer (step S13), and transmits an initialization command for initializing the sub board according to the contents to the sub board. Processing is executed (step S14). Examples of the initialization command include a command indicating an initial symbol displayed on the variable display device 9.

  In step S15, the CPU 56 sets a CTC register built in the CPU 56 so that a timer interrupt is periodically generated every predetermined time (2 ms in this example). That is, a value corresponding to, for example, 2 ms is set in a predetermined register (time constant register) as an initial value. In this embodiment, it is assumed that a value corresponding to 2 ms is set in the time constant register and a timer interrupt is periodically generated every 2 ms.

  When the execution of the initialization process (steps S10 to S15) is completed, the CPU 56 disables the interrupt (step S16), performs the display random number update process (step S17), and then determines the random 1 initial value determination random number. Then, the random number initial value determination random number update process is executed (step S18).

  Next, the CPU 56 makes an interrupt permission state (step S19), and then executes a NOP (non-operation) process (step S20). After executing the NOP process, the CPU 56 sets the interrupt disabled state (step S21), performs the random 3 initial value determination random number update process (step S22), sets the interrupt enabled state (step S23), and step S16. Return to.

  As described above, in this example, the update process of the display random number and the initial value determining random number is repeatedly executed in the main routine. However, the NOP process is executed between the random number 1 initial value determination random number update process and the random number 3 initial value determination random number update process, and the random number 1 initial value determination random number update process and the random number 3 initial value determination A timer interrupt is likely to occur during the random number update process.

  The NOP process is a process for setting a state in which no substantial control is performed during a predetermined period. Specifically, the process is simply a process of adding a predetermined number (for example, “1”) of the program counter (program counter update). Processing). That is, when only the addition of the program counter is performed in the NOP process (program counter update process), no substantial control is executed in the main routine. The “program counter” is a counter in which a value indicating the address of the program area of the storage means in which the processing program to be executed is stored is set.

  In this example, after the interrupt enabled state is set in step S23, a jump instruction or the like is executed until the process returns to step S16 to enter the interrupt disabled state. For this reason, a timer interrupt may occur and the game control process may be executed after the interrupt enabled state is set in step S23 and before the interrupt disabled state is set in step S16.

  The display random number is a random number for determining a symbol displayed on the variable display device 9, and the display random number update process is a process for updating the count value of the counter for generating the display random number. It is.

  The initial value determining random number update process is a process of updating the count value of the counter for generating the initial value determining random number. The initial value determining random number is a random number for determining an initial value of a count value such as a counter for generating a random number for determining whether or not to make a big hit (a big hit determining random number generating counter).

  A game control process described later (a process in which a game control microcomputer controls itself a game device such as a variable display device 9, a variable winning ball device 15, a ball payout device 97 provided in the game machine, or In a process of transmitting a command signal for causing another microcomputer to control, also referred to as a gaming machine control process), when the count value of the jackpot determination random number generation counter makes one round, an initial value is set in the counter.

  Note that when the display random number update process and the initial value determination random number update process are executed, the interrupt disabled state is caused by the timer interrupt described later for the display random number update process and the initial value determination random number update process. This is to avoid conflict with the processing in the timer interrupt processing because the processing is also executed. That is, a timer interrupt is generated during the processes of steps S17, S18, and S22, and the count value of the counter for generating the display random number and the initial value determining random number is updated during the timer interrupt process. Then, the continuity of the count value may be impaired. However, such an inconvenience does not occur if the interrupt is prohibited during the processes of steps S17, S18, and S22.

Next, the game control process will be described.
FIG. 5 is a flowchart showing a 2 ms timer interrupt process. When a 2 ms timer interrupt occurs during execution of the main process, specifically, during execution of the loop process of steps S16 to S23, the CPU 56 starts a timer interrupt process that is started in response to the occurrence of the timer interrupt The game control process is executed at.

  In the game control process, the CPU 56 first executes a power-off process (power-off detection process) for detecting whether or not a power-off signal has been output (whether the power-on signal has been turned on) (step S30).

  Next, the CPU 56 inputs detection signals of switches such as the gate switch 32a, the start port switch 14a, the count switch 23, and the winning port switches 29a, 30a, 33a, and 39a via the input driver circuit 58, and determines their states. (Switch processing: step S31). Specifically, if the state of the input port for inputting the detection signal of each switch is ON, the value of the switch timer provided corresponding to each switch is incremented by one.

  In this embodiment, the continuation time (specifically, the number of confirmations every 2 ms) in which the ON state of the detection signal of each switch related to winning detection or gate passing is confirmed in the switch process (step S31) is set. If it continues for a predetermined period of time, it is determined that the switch has been turned on, and processing corresponding to the switch on is started.

  Moreover, the short circuit alerting | reporting process which performs a predetermined alerting | reporting process based on a switch common monitoring signal is performed (step S32).

  Next, the CPU 56 performs a process of updating the count value of each counter for generating each determination random number such as a jackpot determination random number used for game control (step S33). Further, a process of updating the count value of the counter for generating the random 1 initial value determining random number and the random 6 initial value determining random number is performed (step S34). Furthermore, a process of updating the count value of the counter for generating the random number for determining the random 3 initial value is performed (step S35). And the process which updates the count value of the counter for producing | generating the display random number is performed (step S36).

  Further, the CPU 56 performs special symbol process processing (step S37). In the special symbol process control, corresponding processing is selected and executed according to a special symbol process flag for controlling the pachinko gaming machine 1 in a predetermined order according to the gaming state. The value of the special symbol process flag is updated during each process according to the gaming state. Further, the normal symbol process is performed (step S38). In the normal symbol process, the corresponding process is selected and executed according to the normal symbol process flag for controlling the display state of the normal symbol display 10 in a predetermined order. The value of the normal symbol process flag is updated during each process according to the gaming state.

  Next, the CPU 56 performs a process of setting an effect control command related to the special symbol in a predetermined area of the RAM 55 and sending the effect control command (special symbol command control process: step S39). In addition, a process for setting an effect control command related to the normal symbol in a predetermined area of the RAM 55 and sending the effect control command is performed (normal symbol command control process: step S40).

  Further, the CPU 56 performs information output processing for outputting data such as jackpot information, starting information, probability variation information supplied to the hall management computer, for example (step S41).

  Further, the CPU 56 executes a prize ball process for setting the number of prize balls based on detection signals from the prize opening switches 29a, 30a, 33a, 39a and the like (step S42). Specifically, a payout control signal such as a prize ball number signal indicating the number of prize balls is output to the payout control board 37 in response to detection of a prize based on turning on the prize opening switches 29a, 30a, 33a, 39a, etc. . The payout control CPU mounted on the payout control board 37 drives the ball payout device 97 according to a payout control signal such as a prize ball number signal indicating the number of prize balls.

  And CPU56 performs the memory | storage process which checks the increase / decrease in the number-of-start winning memory | storage number (step S43). Further, a test terminal process, which is a process for outputting a test signal for enabling the control state of the gaming machine to be confirmed outside the gaming machine, is executed (step S44). In this embodiment, a RAM area (output port buffer) corresponding to the output state of the output port is provided. However, the CPU 56 outputs the contents related to the solenoid in the output port buffer to the output port (step). S45: Solenoid output processing). Thereafter, the interrupt permission state is set (step S46), and the process is terminated.

FIG. 6 is an explanatory diagram showing each random number. Each random number is used as follows.
(1) Random 1: Determines whether or not to generate a big hit (for big hit determination, for big hit determination)
(2) Random 2-1 to 2-3 (Random 2): For determining the left symbol of the special symbol (for determining the special symbol, for determining the special symbol)
(3) Random 3: Determine the combination of special symbols that will generate a jackpot (for determining special symbols, determining jackpot symbols)
(4) Random 4: Determine the variation pattern of the special symbol (for variation pattern determination)
(5) Random 5: Decide whether or not to reach when no big hit is generated (for reach determination)
(6) Random 6: Determines whether or not to generate a hit based on a normal symbol (for normal symbol hit determination)
(7) Random 7: Determine initial value of random 1 (for determining random 1 initial value)
(8) Random 8: Determine initial value of random 3 (for determining random 3 initial value)
(9) Random 9: Determine initial value of random 6 (for determining random 6 initial value)

  In step S33 in the game control process shown in FIG. 5, the CPU 56 generates a jackpot determination random number (1), a jackpot determination random number (3), and a determination random number per ordinary symbol (6). Counter is incremented (added by 1). That is, they are determination random numbers, and other random numbers are display random numbers or initial value determination random numbers. In order to enhance the game effect, random numbers other than the random numbers (1) to (9) are also used.

  The counter for generating random 2-2 is counted up when a carry of the counter for generating random 2-1 (when returning to the initial value “0” after becoming “11”) occurs. The counter for generating random 2-3 is counted up when a carry of the counter for generating random 2-2 occurs.

  FIG. 7 is a flowchart showing the determination random number update process (step S33). In the determination random number update process, the CPU 56 first adds 1 to a counter for generating random 1 (a big hit determination random number) (step S401). Then, it is determined whether or not the count value of the counter is smaller than “631” (step S402). If not smaller, that is, if 631 is reached, the value is returned to “0” (step S403). Further, the CPU 56 checks whether or not the count value of the counter for generating the random 1 matches the value set in the random 1 initial value buffer (step S404). If they match, the count value for generating random 7 is read, an initial value determining random number is extracted, the random value is set in a counter for generating random 1 (step S405), and for random 1 Also stored in the initial value buffer (step S406).

  Through the processing in steps S404 to S406, the count value of the counter for generating random 1 is changed every time it makes one round (every 631 counts). Therefore, the randomness of the random 1 is further increased, and it is difficult to play a game aiming for a big hit. As a result, fraud can also be effectively prevented.

  Next, the CPU 56 adds 1 to a counter for generating a random 3 (a jackpot symbol determining random number) (step S407). Then, it is determined whether the count value of the counter has reached “12” (step S408). If it has reached, the value is returned to “0” (step S409). Further, the CPU 56 checks whether or not the count value of the counter for generating the random number 3 matches the value set in the random value initial value buffer (step S410). If they match, the count value for generating random 8 is read to extract an initial value determining random number, the random value is set in a counter for generating random 3 (step S411), and for random 3 Also stored in the initial value buffer (step S412).

  By the processing in steps S410 to S412, the count value of the counter for generating random 3 is changed every time it makes one round (every 12 counts). Therefore, the randomness of the random 3 is further increased, and it is difficult to play a game aimed at a specific jackpot symbol (that is, occurrence of a specific type of jackpot such as a probability variation jackpot). As a result, fraud can also be effectively prevented.

  Further, the CPU 56 adds 1 to a counter for generating random 6 (normal symbol determination random number) (step S413). Then, it is determined whether or not the counter value has reached “14” (step S414). If it has reached, the value is returned to “3” (step S415). That is, the possible range of the counter value for generating random 6 is 3 to 13. Furthermore, the CPU 56 checks whether or not the count value of the counter for generating the random 6 matches the value set in the random 6 initial value buffer (step S416). If they match, the count value for generating random 9 is read, an initial value determining random number is extracted, the random value is set in a counter for generating random 6 (step S417), and for random 6 Also stored in the initial value buffer (step S418).

  By the processing of steps S416 to S418, the set value (initial value) of the count value of the counter for generating the random 6 is changed every time it makes one round (every 3 counts of 13 to 13). Therefore, the randomness of the random 6 is further increased, and it becomes difficult to play a game aiming for the occurrence of a specific hit. As a result, fraud can also be effectively prevented.

  FIG. 8 is a flowchart showing random number 1 and random 6 initial value determination random number update processing (steps S18 and S34). In random number 1 and random 6 initial value determination random number update processing, the CPU 56 adds 1 to a counter for generating random 7 (random 1 initial value determination random number) (step S421). Then, it is determined whether or not the count value of the counter has reached “631” (step S422). If reached, the value is returned to “0” (step S423).

  Further, the CPU 56 adds 1 to a counter for generating random 9 (random 6 initial value determining random number) (step S424). Then, it is determined whether or not the counter value has reached “14” (step S425). If reached, the value is returned to “3” (step S426).

  FIG. 9 is a flowchart showing random number 3 initial value determination random number update processing (steps S22 and S35). In random number 3 initial value determination random number update processing, the CPU 56 adds 1 to a counter for generating random 8 (random 3 initial value determination random number) (step S427). Then, it is determined whether or not the counter value has reached “12” (step S428). If reached, the value is returned to “0” (step S429).

  FIG. 10 is a flowchart showing the display random number update process. In the display random number update processing, the CPU 56 adds 1 to a counter for generating random 4 (variation pattern determining random number) (step S431). Then, it is determined whether the count value of the counter has reached “150” (step S432). If it has reached, “150” is subtracted from the value (step S433).

  Next, 1 is added to a counter for generating random 5 (a random number for reach determination) (step S434). Then, it is determined whether or not the counter value has reached “14” (step S435). If it has reached, “14” is subtracted from the value (step S436).

  Next, the CPU 56 sets the address of the counter for generating the random 2-1 (the left-side special symbol determination random number) to the pointer (step S437). Further, the maximum judgment value of the counter is set (step S438), and the counter update processing subroutine is called (step S439). If the carry flag is set (step S440), the address of the counter for generating random 2-2 (random special symbol determining random number in the middle) is set in the pointer (step S441). Further, the maximum judgment value of the counter is set (step S442), and the counter update processing subroutine is called (step S443). If the carry flag is set (step S444), the address of the counter for generating random 2-3 (the random symbol for determining the right off special symbol) is set in the pointer (step S445). Further, the maximum judgment value of the counter is set (step S446), and the counter update processing subroutine is called (step S447). The carry flag is set when a carry of the count value occurs in the counter update process (when the count value is returned to 0).

  As described above, the counter for generating the left middle right off-set special symbol determining random number is counted up in the counter update processing subroutine. Thus, the program capacity is saved by calling a common subroutine (module). However, random 1, 3, 6, 7 and 8 related to the occurrence of jackpot, determination of jackpot symbol and determination of normal symbol are directly related to the player's interest, so each does not use a common subroutine, but individually The counter is updated.

  FIG. 11 is a flowchart showing a counter update processing subroutine. In the counter update processing subroutine, the CPU 56 specifies a counter to be updated based on the pointer (step S461), and adds 1 to the count value of the counter (step S462). Then, it is confirmed whether or not the count value is smaller than the maximum value (step S463). That is, it is confirmed whether or not the maximum value is reached. If the maximum value is reached, the counter value is returned to “0” (step S464). At this time, since a subtraction process is performed as an internal process of the CPU 56, a carry flag is set.

  FIG. 12 is a flowchart illustrating an example of a special symbol process processing program executed by the CPU 56. The special symbol process shown in FIG. 12 is a specific process of step S37 in the flowchart of FIG. When performing the special symbol process, the CPU 56 performs a variable shortening timer subtraction process (step S310) to detect that a game ball has won the start winning opening 14 provided in the game board 6. If the switch 14a is turned on, that is, if a start winning that causes the game ball to win the start winning opening 14 is generated (step S311), the start opening switch passing process (step S312) is performed, and then according to the internal state. Any one of steps S300 to S308 is performed. The variation shortening timer is a timer for setting the variation time when the variation time of the special symbol is shortened.

  In the start-port switch passing process (step S312), the CPU 56 checks whether or not the start prize memory number has reached the maximum value of 4, and if the start prize memory number has not reached 4, the start prize memory number is set. The number of random numbers such as a jackpot determination random number is extracted by 1, and processing for storing them in a storage area (special symbol determination buffer) corresponding to the value of the number of start winning prizes is performed. Note that extracting a random number means reading a count value from a counter for generating a random number and setting the read count value as a random value. In step S312, random 1 to random 5 are extracted from the random numbers shown in FIG.

  Special symbol normal processing (step S300): Waits until the variable symbol variable display can be started. When the special symbol variable display can be started, the start winning memory number is confirmed. If the start winning memorization number is not 0, it is determined whether or not to make a big hit by the big hit determination module described later as a result of the variable display of the special symbol. Then, the internal state (special symbol process flag) is updated so as to shift to step S301.

  Special symbol stop symbol setting process (step S301): The stop symbol of the left middle right symbol after variable display of the special symbol is determined. In this example, when the result of variably displaying the special symbol is a jackpot, the jackpot symbol is determined according to the value of the jackpot symbol determining random number (random 3). On the other hand, when the result of variable symbol special display is set to be out of place (including reach), the out-of-band design (including reach design) is determined according to the value of the random design determining random number (random 2). Then, the internal state (special symbol process flag) is updated so as to shift to step S302.

  Fluctuation pattern setting process (step S302): A variation pattern (variable display mode) of variable display of special symbols is determined according to a random 4 value. Also, a variable time timer is started. At this time, the left middle right final stop symbol and information for instructing the variation mode (variation pattern) are transmitted to the effect control board 80. Then, the internal state (special symbol process flag) is updated so as to shift to step S303.

  Special symbol variation process (step S303): When a predetermined time (the time indicated by the variation time timer in step S302) has elapsed, the internal state (special symbol process flag) is updated to shift to step S304.

  Special symbol stop process (step S304): Control is performed so that all symbols displayed on the variable display device 9 are stopped. Specifically, it sets to the state where the production control command which shows special symbol stop is transmitted. If the stop symbol is a combination of jackpot symbols, the internal state (special symbol process flag) is updated to shift to step S305. If not, the internal state is updated to shift to step S300.

  Preliminary winning opening opening process (step S305): Control for opening the large winning opening is started. Specifically, the counter and the flag are initialized, and the solenoid 21 is driven to open the special winning opening. Also, the process timer sets the execution time of the big prize opening opening process and sets the big hit flag. Then, the internal state (special symbol process flag) is updated so as to shift to step S306.

  Processing for opening a special prize opening (step S306): A process for sending a production control command for displaying a big prize round to the production control board 80, a process for confirming the completion of the closing condition for the special prize opening, and the like are performed. When the closing condition for the last big prize opening is established, the internal state is updated to shift to step S307.

  Specific area valid time process (step S307): The presence / absence of passing through the V winning switch 22 is monitored, and a process of confirming that the big hit gaming state continuation condition is satisfied is performed. If the condition for continuing the big hit gaming state is satisfied and there are still remaining rounds, the internal state is updated to shift to step S305. In addition, when the big hit gaming state continuation condition is not satisfied within a predetermined effective time, or when all rounds are finished, the internal state is updated to shift to step S308.

  Big hit end processing (step S308): Control for causing the effect control means to perform display control for notifying the player that the big hit gaming state has ended. Then, when the stop symbol displayed in the special symbol stop process (step S304) is a probability variation symbol, the gaming state is shifted to the probability variation state (for example, a probability variation flag indicating whether or not the probability variation state is set). ), The internal state is updated to shift to step S300. It should be noted that the time symbol (for example, the left, middle, and right symbols are aligned with “1,1,1”, which has been determined in advance as the state where the symbols stopped in the special symbol stop process (step S304) are in the time-short state. ), The game state is shifted to the short-time state (for example, a probability change flag indicating whether or not the short-time state is set), and then the internal state is updated to shift to step S300.

  Here, the jackpot determination module will be described. The jackpot determination module uses a jackpot determination table in which a jackpot determination value to be compared with a random 1 value is set. In this embodiment, the jackpot determination values are “3” and “7” at the time of low probability (non-probability variation), and the jackpot determination values are “3”, “7”, “ 79 ”,“ 103 ”, and“ 107 ”.

  In the big hit determination module (big hit determination processing), the CPU 56 first determines whether or not the control state of the game at that time is in a probability change, and if it is in the probability change, the table at the time of high probability in the big hit determination table. The process to decide to use is performed. On the other hand, if the probability change is not in progress, a process of determining to use the table at the low probability in the jackpot determination table is performed.

  Then, the CPU 56 determines whether there is a value that matches the extracted random 1 value in the jackpot determination table. If there is a matching value, the CPU 56 determines that it is a jackpot. Processing to decide not to do.

  As described above, it is determined whether or not to make a big hit. When it is determined that the jackpot is to be won, the CPU 56, in the special symbol stop symbol setting process (step S301), the special symbol at the time of the big hit according to the value of the random number for determining the jackpot symbol (random 3). The stop symbol of the left middle right symbol after the variable display is determined. In this example, it is assumed that the same numerical value as that of the extracted jackpot symbol determination random number is determined as the stop symbol. In other words, the jackpot symbol in which the same numerical value (any one of “0” to “11”) as the extracted jackpot symbol determining random number value (any one of “0” to “11”) is aligned in the middle left and right. The

  In this example, when the stop symbols of the left middle right symbols are aligned with odd numbers of symbols, it becomes a probable big hit (big hit that shifts from the non-probable change state to the probable change state), and the stop symbols of the left middle right symbols are even with the even symbols. In this case, a non-probable big hit (a big hit that does not shift from the non-probable change state to the probable change state) is made. In other words, depending on the type of jackpot symbol, the type of jackpot gaming state (probability variation jackpot, non-probability variation jackpot) is determined. Thus, the jackpot symbol determining random number also serves as a random number for determining the type of jackpot. Note that the types of big hit gaming states are not limited to probable big hits and non-probable big hits, but other types such as short-term big hits may be prepared.

  FIG. 13 is a timing chart showing the relationship between the random 1 initial value determining random number and the random 3 initial value determining random number when the timer interrupt occurs. As shown in FIG. 13, when a timer interrupt occurs between step S18 and step S22 in the main routine, the total number of executions of step S18 since the power-on of the gaming machine is the number of executions of step S22. Since the total number of executions of step S34 and step S35 is the same, the update count of the random 1 initial value determination random number is one more than the update count of the random 3 initial value determination random number. Become.

  On the other hand, as shown in FIG. 13, when a timer interrupt occurs after step S22 in the main routine is executed and before step S18 is executed, the steps S18 and S22 from when the gaming machine is turned on are turned on. Since the total number of executions is the same, and the total number of executions of step S34 and step S35 is also the same, the update number of the random 1 initial value determination random number and the update number of the random 3 initial value determination random number are the same. Become.

  In the above-described embodiment, an interrupt is permitted between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process, and the NOP process is performed. Control is performed so that timer interruptions frequently occur between step S22 and step S22. Therefore, it is possible to prevent the random 1 initial value determining random number and the random 3 initial value determining random number from being always synchronized, and for determining the random 1 initial value when a timer interrupt occurs. The relationship between the random number and the random number for determining the random 3 initial value can be made random.

  As described above, since the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process are set in the interrupt permission state and the NOP process is performed, The timer interrupt process can be executed at a high frequency between the random update process for determining the random 1 initial value and the random update process for determining the random 3 initial value in the main process. It is possible to prevent the random 1 and random 3 initial values from being changed while the random number and the random 3 initial value determining random number are synchronized. For this reason, it is possible to avoid illegally generating a big hit or illegally generating a specific type of big hit such as a probable change big hit by an illegal act such as sending a start winning signal illegally.

  That is, if all the processes in the main routine are performed in an interrupt disabled state, and a random 1 initial value determining random number and a random 3 initial value determining random number are performed in the main routine, the random 1 initial value The determination random number and the random 3 initial value determination random number are always updated as a set in the main routine, and the timer interruption occurs with the total number of updates since the power-on is always the same.

  Also, for example, if no game is being played, the execution period of the timer interrupt process is a substantially constant time (for example, 1.6 ms), and one period of the main routine is also approximately a constant time (for example, 0.2 ms). For this reason, the surplus time in the timer interrupt generation interval (for example, 2 ms) in which the main routine is executed is also a fixed time (for example, 0.4 ms), and is executed in one surplus time in each timer interrupt generation interval. The number of main routines (for example, (0.4 ms / 0.2 ms) = 2 times) can be calculated.

  Therefore, when the random 1 initial value determining random number and the random 3 initial value determining random number are always updated as a set in the main routine, the timer is set according to the elapsed time from power-on (at the start of the random number updating process). There is a possibility that the fraudulent person can know the total number of updates of the random number for determining the random 1 initial value and the random number for determining the random 3 initial value when the interruption occurs.

  Furthermore, based on the update range of random 1 and random 3, it is possible to calculate the timing at which the initial value of each random number is changed simultaneously.

  Thus, for example, when a random means such as a fraudulent board is mounted on a gaming machine and the random 1 initial value determination random number value matches the jackpot determination value, the timing for changing the initial value of random 1 comes If the start winning signal is illegally sent to the game control microcomputer in the CPU 56 by an illegal means such as an illegal board, it is possible to illegally generate a big hit.

  Also, when it is determined whether the jackpot symbol is a probabilistic big hit or a non-probable big hit, the random 1 initial value determining random number value matches the jackpot determination value and the random 3 initial value A game in the CPU 56 by a fraudulent means such as a fraudulent board, aiming at the time when the random 1 initial value and the random 3 initial value change timing arrive at the same time when the value of the random number for determination is a value indicating a probability variation pattern By illegally sending a start winning signal to the control microcomputer, it becomes possible to illegally generate a probable big hit.

  In contrast, in the above-described embodiment, the timer interrupt process is frequently executed between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process. Since the random 1 initial value determining random number and the random 3 initial value determining random number are synchronized with each other, it is possible to prevent the random 1 and random 3 initial values from being changed. Thus, it is possible to prevent the occurrence of a big hit or a probable big hit based on an illegal act such as illegally sending a start winning signal.

  In the above-described embodiment, the interrupt is permitted and the NOP process is performed between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process. However, the interrupt permission state may be set without performing the NOP process. Even in such a configuration, there is room for timer interruption unless the interrupt permission process in step S19 and the interrupt prohibition process in step S21 are described continuously in the control program. , A timer interrupt can be generated between the random 1 initial value determining random number update process and the random 3 initial value determining random number update process in the main process, and the random 1 initial value determining random number The game control process can be executed between the update process and the random 3 initial value determination random number update process. Therefore, it is possible to avoid that the random number for determining the initial value of random 1 and the random number for determining the initial value of random 3 are synchronized when the timer interrupt occurs. Generation of big hits of types can be prevented. However, if the configuration is such that the NOP process is performed, there is a possibility that a timer interrupt will occur between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process. Thus, the game control process can be more reliably executed between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process.

  Further, in the above-described embodiment, the interrupt permission state is set between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process, and the NOP process is performed. However, not only the NOP process but also a delay process for inducing a timer interrupt is executed, a random 1 initial value determination random number update process and a random 3 initial value determination random number update process in the main process, A timer interrupt may be generated during this period.

  FIG. 14 is a flowchart showing a part of the main process when the delay process is performed in the main routine. As shown in FIG. 14, in the main process, the CPU 56 determines the count value K by lottery, for example, in order to determine the delay period after setting the interrupt permitted state in step S19 (step S20a). Next, the CPU 56 adds 1 to the count value of the delay counter (step S20b), and when the count value of the delay counter reaches K (Y in step S20c), the CPU proceeds to step S21 assuming that the delay period has ended. That is, the count value of the delay counter is incremented by 1 from 0, and when the count value K determined in step S20a is reached, the process proceeds to step S21.

  As described above, when the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process are set to be in an interrupt permitted state, a delay period is provided. In addition, it is possible to induce a timer interrupt between the random update process for determining the random initial value 1 and the random update process for determining the random initial value 3 in the main process, and the random update process for determining the initial value 1 and the random update process. 3 The game control process can be more reliably executed during the initial value determination random number update process.

  In addition, as described above, the delay time is determined by lottery and the delay time is determined at random. Therefore, the random 1 initial value determining random number updating process and the random 3 initial value determining random number updating process in the main process are performed. A timer interrupt can be generated randomly between the random number 1 random number update process for determining the random initial value and the random number random number update process for determining the random initial value 3 so that the game control process is executed at random. Can be.

  Note that the delay time in the above example may be a time at which a timer interrupt such as 5 ms occurs multiple times. Further, the NOP process and the delay process may be performed together, and in that case, the total of the execution time of the NOP process and the delay time by the delay process becomes a time at which a timer interrupt occurs a plurality of times. May be. With this configuration, a timer interrupt can be generated multiple times between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process. The difference between the initial value determining random number value and the random 3 initial value determining random number value can be increased.

  Further, in the above-described embodiment, an interrupt is permitted between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process, and the process is performed in a substantially constant period. The NOP process to be completed is configured, but a random number initial value determination random number update process and a random process in the main process are performed in such a manner that a process having a different process period (execution period variation process) is executed according to a predetermined condition. (3) The possibility (probability) that a timer interruption may occur between the initial value determination random number update process may be changed. As the “execution period variation process”, for example, a process in which a process period varies depending on whether or not a carry occurs, specifically, the above-described errant symbol determination random number update process (see steps S437 to S447) can be considered.

  FIG. 15 shows a part of the main process when the random number update process for determining symbols (part of the display random number update process shown in FIG. 10: steps S437 to S447) is performed as the execution period variation process in the main routine. It is a flowchart which shows. As shown in FIG. 15, in the main process, after the CPU 56 enters the interrupt-permitted state in step S <b> 19, the CPU 56 executes the symbol determination random number update process (see steps S <b> 437 to S <b> 447) as the execution period variation process ( Step S20d) and the process proceeds to Step S21. It should be noted that in the off symbol determination random number update process in step S20d, if no carry occurs in updating the left symbol random number (random 2-1) (N in step S440), the medium symbol random number (random) If no carry occurs in the update of 2-2) (N in step S444), or if all the random numbers for the left middle right symbol are updated (after step S447), the process proceeds to step S21 To do.

  That is, in this example, when the left symbol random number (random 2-1) is updated, no carry occurs, and when the left symbol random number (random 2-1) is updated, a carry occurs. If the carry does not occur due to the update of the random number for the middle symbol (random 2-2), and after the carry occurs due to the update of the random number for the left symbol (random 2-1), the random number for the middle symbol ( The execution period of the process differs depending on whether a carry has occurred due to the random 2-2) update.

  As described above, between the random 1 initial value determination random number update process and the random 3 initial value determination random number update process in the main process is set to the interrupt permission state, and when the interrupt permission state is set, In the case of a configuration that executes a process (execution period variation process) with a different processing period depending on a predetermined condition (for example, whether there is a carry or the number of times a carry has occurred), the period in which the interrupt is permitted To change the possibility (probability) that a timer interrupt will occur between the update process of the random number for determining the random 1 initial value and the update process of the random number for determining the initial 3 value in the main process. Can do. Accordingly, a timer interrupt can be randomly generated between the random 1 initial value determining random number updating process and the random 3 initial value determining random number updating process in the main process, and the random 1 initial value determining random number. The game control process can be executed randomly between the update process and the random 3 initial value determination random number update process.

  In the above example, the “execution period variation process” is configured to perform the random symbol determination random number update process (see steps S437 to S447), but the execution period variation process is interrupted and the game control process is executed. Therefore, it is preferable to execute a process that is not executed in the game control process as the execution period variation process. That is, if the game control process is executed in a state where the random symbol update process for losing symbol determination as the execution period variation process is interrupted, and the random number update process for deciding symbol determination is executed within the game control process, the random number update is performed. There is a possibility that consistency between the number of executions of the process and the update value of the random number may not be achieved. In order to avoid such a situation, it is preferable to execute a process that is not executed in the game control process as the execution period variation process. For example, the update process of the random number for determining the notice used for determining whether or not to make a jackpot notice is configured so that the processing period varies depending on whether there is a carry, etc., and the execution period changing process is not executed within the game control process As long as it is executed. Also, for example, the random symbol determination random number update process (see steps S437 to S447) is not performed in step S36 in the timer interrupt process, and is performed only in the main process as the “execution period variation process”. Good.

  In the above-described embodiment, the random 1 initial value determining random number and the random 3 initial value determining random number are both updated by incrementing the count value of the random number generation counter by 1. However, at least one of the update processes may be updated to a random numerical value. For example, at least one of the random 1 initial value determining random number and the random 3 initial value determining random number may be configured to be updated to a numerical value indicated by a random number generation counter that generates randomly. Specifically, when the random 1 initial value determination random number is to be updated randomly, for example, in step S421, a counter for generating the random 1 initial value determination random number (random 1 initial value determination random number) The numerical value to be added to the generation counter) may be a numerical value indicated by a separately provided random number generation counter (for example, a counter whose value is updated in the game control process and the main process). When the random 3 initial value determining random number is to be updated at random, for example, in step S427, a counter for generating a random 3 initial value determining random number (random 3 initial value determining random number generating counter) is generated. The numerical value added to () may be a numerical value indicated by a random number generation counter (for example, a counter whose value is updated in the game control process and the main process) provided separately. If comprised as mentioned above, the randomness of at least any one of the random number for random 1 initial value determination and the random number for random 3 initial value determination can be improved.

  In the above-described embodiment, only one of random 1 initial value determination random number update processing and random 3 initial value determination random number update processing is performed in the game control process based on the occurrence of a timer interrupt. May be. With this configuration, the random 1 initial value determining random number and the random 3 initial value determining random number can be prevented from being synchronized. In the above-described embodiment, in the game control process based on the occurrence of the timer interrupt, the update number in the random 1 initial value determination random number update process and the update number in the random 3 initial value determination random number update process are randomly selected. (That is, a random value is added or updated to a random value). Furthermore, you may make it perform said process together.

  In the above-described embodiment, the random 1 initial value determining random number updating process and the random 3 initial value determining process are performed in one loop process in the main routine (process executed while the loop makes one round). The random number update process is executed once, and the random 1 initial value determining random number and the random 3 initial value determining random number are added one by one, but one loop in the main routine (main process) In the processing, only the random 1 initial value determination random number update process (the process of updating the first initial value numerical data) is performed, and the random 3 initial value determination random number update process (the second initial value numerical data). The random number 1 initial value determination random number update process and the random number 3 initial value determination random number update process are performed at random. It may be. With this configuration, for example, only the random 1 initial value determination random number update process is executed in the first loop process and the second loop process, and the random 3 initial value determination random number is executed in the third loop process. Each initial value determination random number is updated in such a manner that only the update process is executed. With this configuration, the random 1 initial value determining random number and the random 3 initial value determining random number can be prevented from being synchronized. In addition, the random numbers to be updated are not selected at random as described above, but the random numbers to be updated are preferably arranged according to a predetermined order (as a result, it is preferable that the order is not a regular order). It may be selected.

  Further, in the above-described embodiment, only when a carry is generated by updating one of the initial value determining random numbers in the process of updating the random 1 initial value determining random number and the random 3 initial value determining random number. The other initial value determining random number may be updated. For example, only when a carry occurs in the update process of the random number for determining the random 1 initial value in step S18 (the process of updating the numerical data for the first initial value), the random 3 initial value in the subsequent step S22 If the random number for determination is updated (the process of updating the numerical data for the second initial value), and no carry occurs in the update process of the random number for determining the random 1 initial value in step S18, the subsequent steps In S22, the random 3 initial value determining random number may not be updated. If comprised as mentioned above, according to the presence or absence of the carry by the update of one initial value determination random number, it can be determined whether update of the other initial value determination random number is performed, random 1 initial stage Since it can be avoided that the random number for determining the value and the random number for determining the initial value of random 3 are synchronized, the random number for determining the initial value of random 1 and the random number for determining the initial value of random 3 are synchronized. It is possible to prevent the initial values of random 1 and random 3 from being changed.

  In the above-described embodiment, the game control process is executed by the timer interrupt process activated by the timer interrupt generated every 2 ms, but the game control process is executed in the main process, and the game control process You may make it perform the required process (for example, step S17, S18, S22) of step S16-step S23 mentioned above in the remainder time. In this case, for example, in the main process, after the game control process is completed, a loop process for checking a counter for measuring whether a predetermined period (for example, 2 ms) has elapsed from the start of the game control process is executed. Then, if 2 ms has elapsed, it is sufficient to exit the loop process and start the next game control process. And what is necessary is just to perform the process of step S16-step S23 mentioned above within the loop process. Further, after finishing the random 1 initial value determination random number update process (the process of updating the first initial value numerical data) in step S18, the random 3 initial value determination random number update process (the second initial value determination random number update process in step S22) It is only necessary to confirm whether or not a predetermined period has elapsed in the loop process before the process of updating the numerical data for 2 initial values is started. In the case of the above example, since the random number is not updated by the timer interrupt process, it is not necessary to perform the processes of steps S16, S19 to S21, and S23 in the loop process.

  In the above-described embodiment, the big hit determination values are “3” and “7” at low probability (non-probability change), and the big hit determination values are “3” and “7” at high probability (probability change). ”,“ 79 ”,“ 103 ”, and“ 107 ”, but the jackpot determination value may include a plurality of consecutive numerical values such as“ 3 ”to“ 7 ”.

  In this case, specifically, when five consecutive numbers from “3” to “7” are used as the jackpot determination value, the game control means determines that the value of the random number for jackpot determination is the jackpot determination process. It is possible to determine whether or not to make a big hit through two comparison processes of whether or not it is “3” or more and whether or not the value of the big hit determination random number is “7” or less. On the other hand, when the five discontinuous numbers are used as the jackpot determination value, the game control means determines whether the value of the random number for determining the big hit matches each of the five jackpot determination values in the jackpot determination process. Whether or not to make a big hit is determined by five comparison processes.

  As described above, when the jackpot determination value including a plurality of consecutive numerical values is used, the jackpot determination can be performed by determining whether the value of the jackpot determination random number is within a certain range. Therefore, it is possible to reduce the control burden of the determination process for determining whether or not to win.

  In the above-described embodiment, the total number of numerical values included in the random 1 update range is 631 and the total number of numerical values included in the random 3 update range is 12. However, each number (total number) is an example. Any value may be used.

  The pachinko gaming machine of each of the above embodiments mainly gives a player a predetermined game value when the stop symbol of the special symbol variably displayed on the variable display unit 9 based on the start winning is a combination of the predetermined symbols. Although it was a pachinko gaming machine that became possible, if there is a prize in a predetermined area of the electric game that is released based on the start prize, a predetermined game value can be given to the player, or a start prize Even if it is a pachinko gaming machine in which a predetermined right is generated or continued when there is a prize for a predetermined electric combination that is released when the stop symbol of the symbol that is variably displayed becomes a combination of the predetermined symbol Applicable. Furthermore, the game medium is not limited to a pachinko game machine in which a game ball is used, and even if the game medium is a slot machine such as a coin (medal) or the like, it is determined whether or not to make a big hit (big bonus) using a random number. The present invention can be applied when determining the display symbol.

  The present invention is applicable to games such as pachinko machines, and in particular, the initial value determining random number in the jackpot determining random number and the initial value determining random number in the jackpot type determining random number are synchronized with each other. It is useful for preventing and preventing specific types of jackpots from being targeted illegally.
